8 Claims. 1

My invention relates to electrical connectors of the quick detachabletype which are positively locked together when assembled.

In many forms of electrical wiring it is desirable to provide quickdetachable or separable connectors for convenience in servicing, testingor the replacement of portions of such wiring. This is particularlynecessary. as an example, in military aircraft, where damaged wire orcable must be replaced quickly, so that the airplane may becomeserviceable as soon as possible. In such aircraft, it is also desirablethat the separable connections do not pull apart or separateaccidentally as a result of personnel pulling on the wires while usingthem as handhoids or supports when walking or in the performance oftheir duties.

Since weight must be saved in military aircraft to the greatest extentpossible, and since many separable connectors are used in each airplane,it is very desirable that the separable connectors require no extra wireor cable or "slack in order to permit them to be opened or closed. Myseparable connector permits the wires to be actually pulled taut inmaking the connection.

One object of my invention is to provide such a connector which can beassembled without requiring any slack in the wires or cable which itjoins.

Another object of my invention is to provide a separable connector whichcannot be pulled apart or otherwise accidentally separated.

Still another object of my invention is to provide a separable connectorwhich can be readily taken apart manually or with the assistance ofcommonly available tools such as a screwdriver.

A further object of my invention is to provide a separable connectorwhich is easy to manuiacture by mass production methods and is low incost.

I accomplish these and other objects and obtain my new results as willbe apparent from the device described in the following specification,particularly pointed out in the claims, and illustrated in theaccompanying drawing in which:

Fig. i is a perspective view of a separable connector half with opengripper means.

Fig. 2 is a. perspective view of my connector with one gripping means inopen position.

Fig. 3 is a side elevation of the same with both gripping means inclosed position.

Fig. 4 is a bottom. view of the same.

Fig. 5 is a sectional view through 5-5 of Fig. 3.

Fig. 6 is a view of a flat terminal portion.

Fig. 'l is a perspective view of another pair of flat terminal portions.

My separable connector may consist of two identical halves ill and iilawhich are assembled to each other in actual use. as is shown in Fig. 2.In the drawings elements of connector half Illa will be similarlydesignated as half i0.

Each half, as shown in Fig. 1 consists of a barrel, or socket portion iiinto which a wire or cable I! is inserted and attached by either theindentation III or by other well known methods. The extending flattongue I may be made by flattening a tube the end of which forms thesocket ii, and trimming the edges. A recess i5 is provided adjacent thesocket. At the other end of the tongue a u-spring clasp l6, having legsl1 and I8 spaced apart sufficiently to spring clasp the two tonguesections it and Ila, is plvotally mounted by means of rivet i9 as shownin Fig. 2. The rivet i! has a dish-shaped head 20, on the same side ofthe tongue H, as contains the recess i5. It has a diameter sufiicient toallow it to be positioned in the recess i5a of the interlocking halfiila.

The leg i8 of the clasp has an arm II which extends eccentrically of theclasp, so that when the clasp is in the closed position. the U-shapedportion will extend transversely across the tongue sections, supportedby the pivotally mounted arm. At the end of the arm. a stop tab 22 isformed to prevent the clasp from opening more than from the closedposition, at which open position it will engage the edge of the tongue.This facilitates assembly and prevents the clasp from being improperlyclosed.

Because of the spring clasping pressure sometimes required. screwdriverslots 23 and 24 may be provided in the legs i1 and i8 of the clasp, toassist in the opening and closing of the clasps. Thus when it isdiflicult to open and close the clasps by hand the blade of ascrewdriver may be inserted in one of the slots, and a turning coupleexerted in the proper direction, which will cause the clasp to rotateeasily.

To assemble the two halves of the connection together. it is firstnecessary to place the springs in the open position as shown in Fig. 1.The tongues i0 and Illa of the two halves are then placed, one over theother, with the dish shaped head 20a resting in the recess I5, and dishshaped head 20 resting in recess iia. The two ciasps i6 and iBa areclosed by rotating them 90, as is illustrated by clasp iii in Fig. 2.

The U-shaped clasps then grip the two tongues together with strongspring pressure. providing a good "wiping" type oi electric contact. Atthe same time, the rivet heads, locked in the shallow recesses. preventseparation of the two halves as a result of longitudinal or transversestresses.
